TikTok, Spotify, Tinder and many other iOS apps are crashing again due to Facebook problem

A number of popular apps and services, including TikTok, Spotify, Pinterest and Tinder, are currently broken on iOS devices, with early reports suggesting that Facebook is to blame.

There are widespread reports on social media of apps that crash when launched on iPhones and iPads, and associated dropouts on DownDetector.com. The apps can be launched when the device is offline, which is useful in some cases (if you have a lot of music stored on Spotify, for example), but will completely break its functionality in others.

Users do not need to use Facebook to login to an app as it affects their software. There are no similar reports of the same apps crashing on Android devices or the internet.

A similar issue with the Facebook SDK occurred in May and involved dozens of apps. The problems were largely resolved that same day.
